Application and January 18,1906. semi No. 296.681.

To all whom it m/tj/ concern:

Be it known that I, WILLIAM A. WELTY, a citizen of the United States,residing at Waterloo, in the county of Blackhawk and State of Iowa, haveinvented a new and useful Fountain-Pen, of which the following is aspecification.

This invention relates generally to fountain-pens, and particularly to anovel form of feedbar therefor.

The object of the invention is to provide a feed-bar which in a noveland ink that might gather around the pen-point when the pen is nearlyempty, thereby to prevent bleeding and blotting, and also of storing asufficient quantity of in k to kee the main ink-duct moist for quite anexten ed period of time, whereby the vpen will always start to writeupon demand, and thereby obviate the annoyance and loss of time thatensues where the main ink-duct has become dry and refuses to feed theink `to the pen in proper quantities.

A further object is to dispose the air-duct at such point relatively tothe terminals of the feed-bar as to overcome any 4tendency of the ink torun out and soil the outside of the feed, and, further, to relieve themain inkduct or the greater portion of it from the retarding action ofthe air.

With the above and other objects in view, as will appear as the natureof the invention is better understood, the same consists in a novelfeed-bar for fountain-pens, as will be hereinafter fully described andclaimed.

In the accompanying drawings, forming a part of this specification, -andin which like l s's characters of reference indicate correspondingparts, Figure 1 is a view in perspective of a feed-bar constructed inaccordance with the present invention and viewed from the upper sidethereof. Fig. 2 is a View in plan of the under side of the feed-bar.Ifig. 3 isa ransverse sectional view through the feed- Referring to thedrawings, 1 designates the feed-bar, which is provided with a maininkduct 2, that extends practically throughout its entire length and isintersected intermediate of its ends by an air-passage 3, that extendstransversely through the bar, preferably at right angles to its length,and communicates with an air-duct 4, disposed on the under side of thebar in alinement with the practical man- `ner shall be capable ofholding any surplus main duct and that extends from the airduct outwardand communicates lat its forward end with the air, thereby to cause theair to vpass to the main ink-duct by a short and direct passage insteadof having to traverse the entire length of the bar, as is usual. Bydisposing the air-passage at the point shown 1t will lie wholly withinthe pen-section, and thereby minimize the retardin action of the airupon the ink. On each si e of the main ink-duct and extending nearly tothe outer end of the bar and terminating,

preferably, in alinement with the end of the 4 main ink-duct is asubduct or channel 5, the

two constituting storage chambers or reservoirs for holding to retainthe main ink-duct in a moist condition for quite 4an extended period oftime and which w1ll readily flow to the pen the instant the latter isbrought into contact with the pa er.

s will be seen by reference to Fig. 1, there is no dlrect connectionbetween the resera sufficient quantity of ink voirs and the mainink-duct; but there is an indirect one resulting from capillary tractionthat will cause the ink in the subducts to be fed to the main duct whenthe en is in use. In addition to storing the ink fbi` the purpose statedthe subducts will operate to hold any surplus ink that might gatheraround the pen-point when the pen is nearly empty, thereby preventingbleeding and blotting in a practical and positive manner. When a penisproperly combined with the feed-bar and the two are placed within thepen-section, external air will positively be excluded from thereservoirs, inasmuch as these terminate short of the end of the bar,whereby the ink contained therein will be prevented from drying andclogging.

By., the arrangement herein shown the objects sought are secured in athoroughly feasible and practical manner, and experiments havedemonstrated that when a feed-bar is constructed as described the pen,so long vas the reservoirs contain any ink, will always start instantlyto write, thereby obviating a serious objection urged by many againstthe use ofl fountain-pens.

I claimc 1. A feed-bar provided with a longitudinal IOO ink-duct andwith an elongated longitudinally-disposed ink-reservoir on each side ofthe duct, said reservoirs being closed at the bottom and out ofcommunication with the IIO dinal ink-duct extending througghouit presti-:my

cally the entire len th of the ar, said bar having a short aiI- uct inits other side.. and having an airassage connectingv the ducts, and saidbar a so having elon ated ink-reser- 1o voirs at the sides of the inkuctand out of dinectcoxmnmnicationx with said duet and the air-duct, thebottoms of said receptacles bel in permanently closed.

n testimony that I claim the foregoing as in the presence of twowitnesses.
